Polarized Sunglasses – Working, Advantages, Conclusion

Polarized Sunglasses


The polarized sunglasses are capable to reduce glare from the surface like water, snow, and glass. For this result, the true colors of the object are distorted by wearing them, and then it’s made it harder to distinguish them.

They are a great option for anyone who spends lots of time outdoors. It helps them to protect your eyes by reducing glare. There are also many different options for protecting your eyes from glare and these polarized lenses are in one of them. Just like, As you’re protecting your skin from the harmful rays of the sun you have also need to protect your eyes as well.

How They are Working:

Our earth’s most common source of light is the sun which emits the un-polarized light, where every photon has a unique orientation. If light strikes a reflective surface, such as a body of water. The photons are orients horizontally are more likely to reflect.

The polarized sunglasses are work to preventing the light glare by hitting directly in your eyes by blocking reflections. The polarized lenses filter the sunlight that enters your eyes and allows the wearer to see in a different way.

It’s coated with a thin film that absorbs horizontally polarized lights. It protects you from becoming by the reflection of sunlight.

The polarized sunglasses filter horizontally-oriented photons. They help little when the glare is not coming from the ground or something parallel to it(like you still have to watch out for mirrors, or windowpane reflection).

The color filter reduces light transmission that lets the lenses enhance or soften the effect of a particular color to the wearer. The different colored polarized lenses cater to different lighting.

Brown colored lenses:

They are best for bright sunshine days or lightly cloudy weather conditions.

Grey colored lenses:

It helps to filter all wavelengths of visual light evenly across the color spectrum.

Deep green colored lenses:

It’s the combination with the deeper density of grey. It offers superior protection in a bright sunshine environment.

Yellow-colored lenses:

These lenses are referred to as “blue-blockers”. It greatly increases the contrast and depth of vision.

Rose-colored lenses:

They help to sharpen the focus and contrast in a variety of light conditions. It’s useful for the patient who suffers from migraines.

Light-colored sunglasses may reduce brightness and improve wearer comfort, but will not eliminate glare like polarized lenses. Polarized lenses can play an important safety role for the driver, especially in the morning and evening sunlight. Wearing polarizers can almost eliminate the dangerous blurred vision reflected on bright flat surfaces (such as water, wet roads, sand, snow, car hoods, and windshields).

What are the advantages of polarized sunglasses?

A polarized lens offers the following advantages over non-polarized lenses. Our eyes aren’t constantly challenged by glare, it is easier to view objects in bright conditions. Enhances clarity of vision and contrast for ground-level objects and for seeing into water.

1.Better visual comfort and reduced eye strain

The glare is composed of parasitic reflections that disturb the vision and force to squint the eyes in an attempt to see more clearly. When it is recurrent, it becomes very quickly annoying. This is especially the case when you are at sea (on a boat) or in the mountains (when the snow surrounds you). Wearing polarized lenses then helps to see correctly without the need to make any effort!

2. An asset for outdoor sports

The visual comfort provided by the polarizing glass also makes it perfectly suited to outdoor sports. At sea, boating and regattas are sports activities where polarized lenses are essential, as well as in the mountains, and even more so when competing for visual acuity and the improvement of the depth of the field of vision. But water and snow are not the only surfaces on which light can dazzle, and the sports that can enjoy these useful lenses are numerous (cycling, golf, hiking, etc.).

3. Help for certain driving conditions

The other reflective surfaces and a road is just a place where they are! When driving, the sun’s rays can reflect both on the pavement and on the windows of the vehicles around us. Polarizing glass, therefore, helps prevent glare in this situation, which can prevent or better manage dangerous situations. The visual comfort it brings is also an advantage to perceive all the information.

Other Conclusions:

LCD panels are emitted vertically polarized light That’s the reason it can be hard to use iPhone in landscape mode. Reading texts on LCD/LED screens with polarized sunglasses on is sometimes very difficult or might be impossible. The better brands of sunglasses are often polarized and offer UV protection as well, but just because the glasses are polarized it doesn’t mean that it offers UV protection too. The polarized sunglasses offer better protection against the harsh light and glare but it’s may not work well in all situations. Dark sunglasses without UV protection may do more harm than good because the dark of the lens will cause the pupil to dilate, thus destroying the UV rays entering the inside of the eye It also increases your visual comfort that’s why eyes aren’t constantly challenged the glare.
